Posterior cricothyroid ligaments

The cricothyroid ligaments are connective tissue formations that are located between the posterior surface of the thyroid gland and the cricoid. They consist of fibrous connective tissue that forms dense cords.

The cricothyroid ligaments perform several important functions. Firstly, they provide fixation of the thyroid gland in the neck. This allows the thyroid gland to maintain its position and prevents it from moving when the head or body moves.

Second, the cricothyroid ligaments play a role in regulating blood flow to the thyroid gland. When the body position changes or during physical activity, the pressure in the vessels of the thyroid gland changes, which can lead to disruption of the blood supply to this organ. The ligaments help maintain normal blood supply to the thyroid gland by changing their thickness and elasticity.

Thirdly, the cricothyroid ligaments are involved in the metabolism between the thyroid gland and surrounding tissues. They ensure the supply of oxygen and nutrients to the thyroid gland and the removal of its metabolic products.

Thus, the ligaments of the cricothyroid posterior glands are important anatomical structures that perform a number of important functions in the human body. Disruption of their work can lead to various diseases of the thyroid gland and disruption of its functioning. Therefore, it is important to understand how they work and how to keep them healthy.

The ligaments of the cricothyroid, or cricoglossa, are five fibrous formations that pass through the thickness of the lingual arch perpendicular to its upper surface and are located at the base of the tongue in its posterior section. All fiber formations are named by their number. There are more ligaments in the back of the tongue. They are formed predominantly by transversely striated smooth muscles.

The fibers of the first two (1st and 2nd) are well expressed in the thyroid gland, where a tortuous duct is located between them. The fibers of the other three (3rd, 4th, 5th) are located behind this duct in the substance of the gland itself, located between the thyroglossomal muscle-tendon plate and the facial surface of the posterior wall of the larynx. The fibrous ligament of the thyroid gland (5th), running in the anterior section from the lateral protrusions of the base of the tongue to the frenulum, also received
